BACKGROUND

The transfer of verbal dictation to a concise written format is an integral part of business in many parts of society. For instance, due to the increasing amounts of audio medical records, the medical transcription industry is currently estimated to be a multibillion dollar industry. With the steady increase in size and complexity of healthcare and the desire to minimize costs associated with routine practices, there is a large push to automate routine practices, such as dictation and automatic speech recognition (ASR).

The final documents generated by transcription services differ greatly from the initial ASR output due to a number of inherent problems. Briefly, in addition to problems with the doctor's speech and common ASR problems (e.g., disfluencies omission of function words, and wrong word guesses), there are conventions used in the final document which are generally not dictated (e.g., section headings, preamble, enumerated lists, medical terminology, and various pieces of additional structure). Traditional ASR has not focused on some of these issues, which are extremely important in fields such as medical transcription that have a specific format and high degree of specialization.

III. Aspects of Systems and Methods

A. Verbal Records

A plurality of verbal records according to an exemplary embodiment of the present disclosure may comprise any type of verbal recording or translation to text thereof. For example, a plurality of verbal records may contain any number of unprocessed verbal recordings, verbal recordings processed through an automatic speech recognition engine, or a copy of any one of the verbal recordings described herein translated into a text format. Further, a plurality of verbal records may include sets of verbal records designated for training and/or a set of verbal recordings designated for evaluation purposes.

Turning to FIG. 4, exemplary verbal records 402, of an embodiment of a system for analyzing verbal records 400, designated, or amended, for training according to an embodiment of the present disclosure may include one or more part-of-speech (POS) tag 404. Further, the verbal records 402 may additionally comprise punctuation 406, such as commas and periods. In at least one embodiment, verbal records 402 labeled for training may be processed (such as by embodiments of a system of the present disclosure) in duplicate with only one copy of the duplicate record being processed to include punctuation. For a first training record of feature instances, according to an embodiment of the present disclosure, features can simply be extracted from the post-regular expression (regex) file. For the second training record, the same post-regex file may be used as in the first training record, followed by processing with a POS tagger, a chunk parser, and then the extraction of appropriate features.

B. Format

According to at least one embodiment of the present disclosure, the verbal record may be translated using an embodiment of a system for analyzing verbal records of the present disclosure. The translated record may in some instances be compared and/or aligned to a translation performed by one or more transcriptionist. In at least one embodiment, the translated record from an embodiment of the system and/or method of analyzing verbal records as described herein is in XML format.

C. Regular Expression Matching

In at least one embodiment of a system for analyzing verbal records 500, as seen in FIG. 5, the system 500 may be capable of processing a subset of verbal records 502 through modification of the verbal (or text translated) record 502 by adding or subtracting a structural feature 504 or a list feature 506. The processor of an embodiment of a system for analyzing verbal records may look for at least one pattern 508. Exemplary patterns 508 according to the present disclosure may include information such as punctuation, headings, medical or legal terms, numbers, quantity indicators, frequencies, durations, and indications of a number. The verbal record 502 from which at least one pattern 508 is identified may be modified to indicate the presence of a pattern 508 and the location within the verbal record 502 of the pattern 508. Additionally, the at least one pattern 508 may be used singly, or in combination with additional patterns 509, to identify the location of a structural feature 504 or list feature 506. Further, the at least one pattern 508 may be used in combination with a template 510 or library of templates to determine the appropriate structural feature or list feature for use with the applicable verbal record 502.

Turning to FIG. 6, an embodiment of a verbal record having an a verbal feature identifying a list feature, may be adapted to incorporate the list feature, in an embodiment of a method for analyzing verbal records 600 of the present disclosure. The steps in the adaption method may include normalizing some or all of the identified numbers into a common format (such as one to 1) (exemplary normalizing step 602), correction of simple textual conversions 604 (such as # for to #4) (exemplary correction step 604), searching between headings to a numerical indicator (# or number) followed by a number (exemplary searching step 606). Following the identification of a numerical indicator followed by a number, the first number sign may be demarked as the beginning of a list (exemplary demarcation step 608) and the last identified number in the list feature is identified as the end of the list (exemplary identifying step 610). Following the identification of the list, errors are corrected in at least one exemplary embodiment (exemplary correction step 612).

Exemplary embodiments of method 600 may also comprise one or more additional modification steps 614-618. First, lists which do not start with “1” are corrected (exemplary correction step 614). Second, numbers which are missing from the normal progression in as identified in the list are added where missing (exemplary addition step 616). Lastly, a search may be performed between the end of the list and the next identified structural feature (such as a heading) (exemplary searching step 618).

In an exemplary embodiment of a method of the present disclosure, medication lists as found in at least one verbal record are identified by searching the record between identified headings to find the number of times that a medication, a quantity, or a frequency is detected. In at least one embodiment, if there is at least one medication present between headings, along with one or more frequency or quantity, then a medication list is designated.

D. Feature Extraction

According to at least one aspect of a verbal feature of the present disclosure, the verbal feature may be a word feature or a phonetic feature, such as those included in Table 1. In an exemplary embodiment, a word feature may include a target word and/or a word stem, and a phonetic feature may include a defined number of syllables, a syllable duration ratio (calculated by dividing the duration of the word by the number of syllables), pause duration (the pause between a target word and the next word), and a pitch value. For at least one embodiment, the pitch (F0) value may be determined between every 5 milliseconds and 20 milliseconds, such as about every 10 milliseconds. From the F0 measurements, variables are determined, which include the (1) maximum F0 of the target, (2) minimum F0 of the target, (3) the change in F0 (delta F0) between the previous word to the target word, and (4) the F0 change at the final boundary of each word (boundary F0)

TABLE 1 Features Feature Number Feature Name 1-5 The window of 5 words  6-10 POS 11-15 Stems 16 The number of syllables in the 3rd word 17 The ratio 3rd word's syllable duration to the average of the previous 10 18 The pause duration after the 3rd word 19 The difference between the MaxF0 of the 2nd word and the 3rd word (DeltaF0) 20 The Maximum F0 of the 3rd word 21 The Minimum F0 of the 3rd word 22 The F0 change in the 3rd word boundary 23 The number of syllables in the 4th word 24 The ratio of 4th word's syllable duration to the average of the previous 10 25 Delta F0 of the 4th word 26 Max F0 of the 4th word 27 does this line have chunk information: yes 28 does this line start with a shallow-level chunk: nx 29 does this line start with a deep-level chunk: nx 30 does this line end with a shallow-level chunk: no 31 does this line end with a deep-level chunk: no 32 The presence of punctuation after the 3rd word (class)

1-15: Words, POS, Stems

Features 1-5 are illustratively five (5) word windows that are looked at for each instance In at least one embodiment of a system of method of the present disclosure, an instance may be an identified subset of verbal records. Features 6-10 and 11-15 are the part of speech (POS) tags and stems of the same five words, respectively. The POS may tell how the word is used, i.e. verb, noun, adjective, etc. The stems are the roots of the words with any suffixes removed from the ends. For example, should the actual point of possible punctuation be between words 3 and 4, so it may be expected that words closer to that will be more important to the processor in making its decisions. In such an example, features 1, 5, 11, and 15, may be ignored so that the system may only need to consider the POS of the words at either end of the window. In at least one embodiment, feature 7 may be ignored as well as the POS of the second word, feature 13, and the stem of the third word. Only for the fourth word, the word after the target for punctuation, all of the “word” features are considered. The same combinations are used for each of the features in all three of the tests in Table 2.

16-26: Phonetic Features

The phonetic features may be broken down into two categories: those that deal with speech rate, and those that deal with fundamental frequency (F0) or tone. In at least one specific embodiment, all of these features deal with either the 3rd word (features 16-22) or the 4th word (23-26) in the window. Generally, the same combinations for these features are used regardless of which training method is being employed for a given test with one illustrative exception. Feature 16, the number of syllables in the third word, may be ignored in either case, as are 20-21, the maximum and minimum F0 for the third word. These features, in at least one embodiment, may be extracted for the purpose of constructing other features, namely features 17 and 19 (technically, the minimum F0 was not needed for feature 19). For the “LODO-trained” tests feature 23 was also ignored. For the “self-trained” tests, feature 26 was again ignored.

27-31: Syntactic Features

In an exemplary embodiment, features 27-31 may provide an embodiment of the processor with syntactic information about the instance in question. All of these aforementioned features may prove to be useful in all testing conditions.

E. Formatting

According to at least one embodiment of the method of processing dictation 700 according to the present disclosure (See FIG. 7), initial punctuation and formatting determinations are made (exemplary determination step 702). Following the determination of POS tags and chunks, according to at least one embodiment, an initial punctuation is introduced (exemplary introduction step 704).

An exemplary computer-implemented method of processing dictation 200 may be used in several different technology and service areas. For example, exemplary method 200 may be used in healthcare applications, such as medical dictation, legal transcription, automatic real-time voice translation, call routing, voice dialing, and content-based audio search.

Table 2 provides results for all doctors for three different tests. One utilizing the overlap metric and “LODO-training” in the first column, one using overlap and “self-training” in column two, and the final combines “self-training” with Levenshtein Distance. The table shows the recall, precision, and precision-weighted f-score, in percentages, for all doctors for each test, as well as the combined results for each test. These results reflect the at least one settings for each type of test on our data to date.

When considering which settings may optimize transcription results, the tests in Table 2 will be referred to. It is possible to get better results for a single doctor at a time with different combinations of settings and features. The default settings of the IB1 nearest neighbor algorithm and Gain Ratio feature weighting have proven to be the best settings for all tests we have run to this point. The decision about the global metric for this dataset, despite the range of options available to an embodiment of the processor, is essentially binary: overlap or Levenshtein Distance. These two metrics can both produce acceptable results, depending on a number of factors. The metric is controlled using the −m

v

(in this case the value should be either L for Levenshtein Distance or O for overlap) in the command line call. The amount of training data available/employed in the test should be considered when making this decision. Generally for our data, overlap performs better with large amounts of training data, whereas Levenshtein can perform well with smaller or larger amounts. Another potentially important factor is time. Running identical tests, changing only the metric as in tests 2 and 3 from Table 2, overlap tests will go much faster than Levenshtein.

Levenshtein Distance can produce the best results for some doctors, and overlap for others. As you can see in Table 2, doctors A, D, E, F, G, H, and K have better results for the overlap tests, but Doctors B, J, and M have better results in the Levenshtein test. For some doctors, the difference is negligible, but for doctors like F and B, there is quite a difference.
